Notes

Don't suggest me to use \pstRotation as I already know it and it is not my interest. You might suggest me to use ([angle=30,nodesep=]{B}A), but the problem is that nodesep must be assigned with an absolute value. It might be a good idea to add a new key, for example, relnodesep to ([angle=30,...]{B}A) syntax so we can solve this problem by just writing ([angle=30,relnodesep=1]{B}A).
